连接到Redis

主要分为运维人员的连接和程序的连接

本机非密码连接

#redis-cli

跨主机非密码连接

redis-cli -h HOSTNAME/IP -p PORT

跨主机密码连接

redis-cli -h HOSTNAME/IP -p PORT -a PASSWORD

shell脚本写入数据到Redis

[root@centos8 ~]##cat redis_test.sh
#!/bin/bash
NUM=100000
PASS=123456
for i in seq $NUM;do
        redis-cli -h 127.0.0.1 -a "$PASS" set key${i} value${i}
        echo "key${i} value${i} 写入完成"
done
echo "$NUM个key写入到Redis完成"  

python连接方式

[root@centos8 ~]#yum -y install python3 python3-redis
[root@centos8 ~]#cat redis_test.py 
#!/bin/env python3 
import redis
#import time
pool = redis.ConnectionPool(host="127.0.0.1", port=6379,password="")
r = redis.Redis(connection_pool=pool)
for i in range(100):
    r.set("k%d" % i,"v%d" % i)
#   time.sleep(1)
    data=r.get("k%d" % i)
    print(data)

[root@centos8 ~]# python3 redis_test.py
......
b'v94'
b'v95'
b'v96'
b'v97'
b'v98'
b'v99'
[root@centos8 ~]#redis-cli 
127.0.0.1:6379> get k10
"v10"
127.0.0.1:6379>
